Transmission and Hydraulic System Details for the John Deere 4955

The John Deere 4955 is equipped with a PowerShift transmission, offering a total of 16 forward and 4 reverse gears. This transmission allows operators to switch gears without needing to stop or clutch, ensuring smooth operation and quick response. The gear shifting is handled by a dual-range lever, which helps improve productivity during field operations.

The hydraulic system on the 4955 is designed to provide robust power for demanding tasks. The tractor features a closed-center hydraulic system with a flow rate of up to 29.6 gallons per minute (gpm). The system supports a maximum pressure of 2,250 psi, delivering reliable performance for heavy-duty implements and attachments.

With a load-sensing hydraulic pump, the John Deere 4955 adjusts the flow of hydraulic fluid according to the demand, reducing fuel consumption during light-duty tasks. The system is complemented by an open-center valve block that ensures smooth operation and prevents unnecessary strain on the pump, ensuring long-term reliability.

The John Deere 4955 also offers a draft control feature, enabling the hydraulic system to respond to changes in implement load. This improves the accuracy and efficiency of fieldwork, particularly when operating plows, harrows, or other soil-engaging tools.

For maximum control, the tractor’s rear hitch is equipped with an advanced three-point linkage system that provides precise implement adjustments. The hitch has a lifting capacity of 8,800 lbs, supporting a wide range of equipment without sacrificing stability or control.

John Deere 4955 Maintenance and Service Considerations

To maintain the John Deere 4955 in optimal condition, regular servicing is crucial. Follow these guidelines to ensure longevity and performance.

Engine Maintenance

• Change the engine oil and filter every 250 hours of operation or annually, whichever comes first.
• Inspect the air filter regularly. Replace it if it shows signs of wear or clogging, typically every 500 hours of operation.
• Check and clean the fuel system, including fuel lines and injectors, at least once a year.
• Monitor coolant levels and ensure the system is flushed and refilled every 2,000 hours or two years.

Transmission and Hydraulic Systems

• Check transmission oil levels and top off if necessary. Replace the fluid and filter every 1,000 hours.
• Inspect the hydraulic system for leaks, and ensure that hydraulic oil is replaced every 1,500 hours of operation.
• Ensure proper functioning of the PTO (Power Take-Off) system, adjusting as needed to prevent wear.

Tires and Suspension

• Check tire pressure regularly to avoid uneven wear and damage. Proper pressure should be maintained based on load requirements.
• Inspect suspension components for wear, especially the front axle, as it takes on significant strain during operation.

Electrical System

• Inspect battery terminals for corrosion. Clean and tighten connections as needed.
• Check all electrical wiring for signs of wear or exposure. Repair as required to avoid failure during operation.

General Inspection

• Conduct a full tractor inspection before each season. Look for leaks, loose bolts, or any parts that require tightening or lubrication.
• Lubricate all moving parts, including steering joints and linkages, according to the manufacturer’s recommendations.
